Before he rose to fame as the mug in the middle of "
Have I got News for You", and presenter of shows to embarrass celebrities with what they did before they were famous, I believe that Angus Deayton worked in amongst other areas the adult film business (at least according to clips he shows of himself on some of these shows).
He also created the BBC Radio 4 comedy series Radio Active, "Britain's first national local radio station", with Geoffrey Perkins (now I believe high up in BBC Light Entertainment). They also did a translation of this to BBC Television called KY TV.
